[R] Is there a way to get R script line number

[Brad P]

Hello,

Is there a way to get the current line number in an R script?

As a silly example, if I have the following script and a function called
getLineNumber (suppose one exists!), then the result would be 3.

1 # This is start of script
2
3 print( getLineNumber() )
4
5 # End of script

Thanks for any ideas!
